REVERSIBLE WINDOW-SASH- Specification of Letters Patent.

Application .led July 27, 1905.

Y To all whom it may concern:

Be it known that I, EDWARD J. PETER- BUsoH, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new .and useful Improvements in ReversibleWindow-Sashes, of which the following is -a specification.

My invention relates to improvements in reversible window-sashes, and has for its primary object to provide a simple, cheap, and effective construction such that a verticallyslidable sash may be turned `or reversed upon a transverse pivotal aXis to present to the interior of the building the surface normally presented to the exterior thereof, so that the window may be readily cleaned.

Another object .of my invention is to provide in such a device improved means for guiding the window in its sliding movement and locking the window in .any position `of angular .adjustmenaas for purposes of ventilation, to provide a novel means yof attachment of the weightcord to the window-sash, and to provide a generally improved and efcient reversible Window-sash construction which may be manufactured at low cost and readily installed.

In the drawings, wherein I have illustrated an embodiment .of my invention, Figure 1 is a view, generally in elevation, of afragment of a window-sash and its appurtenances with arts broken .away upon line 1 1 .of Fi 5.

ig. l2 is asimilar view of `an .opposite ag- .ment of the window with `a little less of the frame and the .sash broken away. Fig. 3 is an elevation of a fragment of a window with parts broken away on line .3 3 -of Fig. 6. Fig. 4 is an edge view of the window-sash. Fig. 5 is a cross-section .on line `5 5 of Fig. 1. Fig. 6 is a cross-section on line 616 of Fig. 1. Figs.

y7 .and '-8 .are .details vof an operatingecam, and

Figs. 9, 10, and 11 are .details of a cord-block construction.

Throughout the .drawings like numerals .of

reference refer always to like parts.

Referring now Ato the drawings, 15 indicates in general the window-frame of Aany suitable thereof, as shown at 18 and 1.9,. These grooves 18 .and 19 lI will respectively designate for identification .as the guidestrip groove and the vcord-block groove. For definition of direction herein I will arbitrarily designate a .direction ncrosswise of the .surface .of the window-glass as lateral .and the .direction at right angles .to the plane .of the glass as transverse to the sash.

The windowssash (general-ly indicated at 20) is pivotally suspended in lateral trunnions arranged centrally of the height of the sash, said trunnions being connected with the weight-cord, Vso that they .are .capable of ver.- tical movement to permit the raising and lowering lof the sash.

The equipment Iof both sides of Veach Sash is alike, so description of .one .side will be understood as applying to all.

Specifically, -21 indicates .a metal hush-lng extending laterally through the side piece .Of the sash, midway the height thereof.

V.22 indicates a trunni on secured at its later.- ally `outer .end to a cord-block 2.3 ofconstruction to be described, said cord-block being arranged for vertical movement in the cordblock groove 19 and being attached to the weight-cord 24, which passes .over .the .pulley 17 and :at its vopposite extremity is connected to the usual `sash-weight 25, sliding the weightway 1-6,

The .cord-block .construction which I prefer to employ is specifically shown inFigS. .9 to 11 and comprises specifically an elongated body .of suitable size, provided with the threaded aperture 23a, which receives the threaded endof the tnunnion `22, and-provided at its upper end with a .cord-receiving groove 231, into which laterally proj ect a plu-` rality of sharp ribs 23. ,At its inner end the groove 23h communicates with `an .aperture 23d, .extending ,through the back of the block at yright angles to the groove 23h. To .attach the weight .cord or rope, :the end thereof is passed through `the aperture 23d.. The no; e is then sharply bent and hammered into t e groove .23", .so that the ribs 23c engage firmly therewith, and the portion of `.the cord pro jecting through the aperture 28d is .cut ofi. It will be .aparent now that the meeting edges .of the @frame and sash being ilush -or flat thesash 20 maybe rotated .upon the trunnions 22 to turn the window to .any angular IOO i 65 adjusted position. v Y

position desired or to reverse it so that its normally outer surface is turned inward'. It

will also be apparent that the sash may be slid vertically, the cord-block 23 sliding in the corresponding groove 19 and the sash being balanced, as usual, by the weight 25. Means are also provid ed for guiding and preventing the reversal or pivotal movement of the sash during its sliding movement, such means preferably comprising in general a longitudinal strip seated in a suitable recess in the sash and arranged for movement into and out of engagement with the guide-strip groove 18 of the window-frame 15.

Specifically, 27 indicates the guide-strip, which is preferably a relatively thin elongated metal piece of some flexibility seated edgewise in a recess 28 in the window-sash 20, so located that when the sash is in normal position said strip registers with the guidestrip groove 18 of the frame. The strip 27 preferably extends from substantially the top to substantially the bottom of the sash.

Suitable means operable from within the building are provided for controlling the movement of the strip 27 into and out of position to engage with the groove 18, such means being herein shown as comprising an eccentric or cam 29, circular in shape, engaging a corresponding aperture 30 in the strip 27 and carried by an operating-stem 29', extending transversely of said sash to the inside thereof.

Preferably the stem 29 is mounted for rotation in a bushing 31 in the window-sash and is suitably flattened, as at 29, (see Fig. 2,) to receive a suitable key or the like, by which the stem and eccentric may be turned to move the strip 27 into or out of the recess 28. To maintain the edge of the strip 27 vertical during its movement under `the influence of the cam, springs acting upon points adjacent the ends of the stri are provided, such springs being herein in icated at 32 as flat leaf-springs secured in the recess 28 of the sash.

It will be apparent that when the cam 28 is turned to the position shown in full lines in Fig. 3, throwing the strip 27 into engagement with the groove 18 of the window-frame, the sash cannot be pivotally turned upon its trunnions 22, but may be slid vertically, being guided by both the guide-strips and the sash-cord block. If, however, the cam 29 be rotated to cause the withdrawal of the strip- 27 into its recess against the tension of the springs 32, the sash maybe freely turned upon its trunnions.

If it be desired to lock the sash in an angular position for purposes of ventilation or otherwise, the sash may be adjusted to any desired angle and the cam 29 then turned to force the strip 27 into frictional engagement with the frame to maintain the sash in such Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a window-sash construction, a frame, a sash, means vertically slidable relative to the frame, to which the sash is'pivotally connected, and a spring-pressed flexible means for guiding the sash vertically and preventing its pivotal movement and a means operating against the tension of the spring for removing the guide.

2. In a window-sash construction, a frame, a sash, means vertically slidable relative to the frame, to which the sash is pivotally connected, and means for reventing pivotal movement of the sash and guiding said sash vertically, comprising a groove in one ofthe sash and frame members, and a springpressed flexible guide-strip for engagement therewith carried by the other member, said guide-strip being automatically movable into engagement with said groove by means of a spring and a hand-operated means for positively moving it out of engagement with said groove.

3. In a window-sash construction, a frame, a sash, means vertically slidable relative to the frame, to which the sash is pivotally connected, and means for reventing pivotal movement of the sash and guiding said sashl vertically, comprising a groove in one of the sash and frame members, and a springpressed flexible guide-stri in normal engagement therewith carried y the other mem ber, said guide-strip being automatically movable into and out of engagement with said groove, and means for moving the guidestrip out of said groove and retaining the same out of engagement against the tension of the spring.
